* For a single calculation, calculation error is ±1 at the 10th digit. (In the case
of exponential display, calculation error is ±1 at the last significant digit.) Errors
are cumulative in the case of consecutive calculations, which can also cause
them to become large. (This is also true of internal consecutive calculations that
are performed in the case of (( x

),

, x!,

, nPr, nCr etc.)
In the vicinity of a function’s singular point and point of inflection, errors are
cumulative and may become large.
Replacing the Battery
